	4	To understand modern approaches to component implementation technologies.

Element 1
Title	In-class Viva and Presentation (Business Process Model)
Task details	A case study accompanies this section of the assignment. It describes the requirement for a system within a business context. You will need to make assumptions in the course of constructing your models. Ensure you submit a list of these assumptions with your assessment elements as appropriate. If you are at all unsure about the case study description you should ask questions within the seminars/workshops. The Tutors will be moderating the discussion boards. The diagrams must be completed using a CASE tool (starUMLis a suitable tool).You need to present the BPM elements of your work to your tutor and be able to answer questions.
Marking Guide	Criteria	Issues	Mark	Marking breakdown where appropriate
	Business Process Model	A Process Model with appropriate tasks.	5

Element 2
Title	In-class Viva and Presentation (Use Case Models and Business Concepts)
Task details	A case study accompanies this section of the assignment. It describes the requirement for a system within a business context. You will need to make assumptions in the course of constructing your models. Ensure you submit a list of these assumptions with your assessment elements as appropriate. If you are at all unsure about the case study description you should ask questions within the seminars/workshops. The Tutors will be moderating the discussion boards. The diagrams must be completed using a CASE tool (starUMLis a suitable tool). You need to present the Use case diagram and the Business Concepts diagram of your work to your tutor and be able to answer questions.

Grade descriptors
In addition to the assessment criteria above the following table may assist you in understanding how we arrive at your final mark. Indeed your final mark should agree with the following grade descriptors, but note that the assessment criteria are the main means of assessment.
Mark	Descriptor
0-39%	Limited conceptual understanding with possible structural deficiencies.  Restricted use of theory within module.  Inappropriate argument leading to unreliable and invalid conclusions/recommendations
40-49%	Some confusion in purpose & aims of evaluation.  Some overall structure and conceptual understanding. Fair use of theory but arguments sometimes irrelevant, illogical or with unsupported assertions.
50-59%	Demonstrates a limited but accurate level of understanding presented in a mostly descriptive manner. The answer contains relevant interpretation and critical understanding especially at the upper end of the marking range.
60-69%	Demonstrates accurate knowledge and understanding of the subject presented in a coherent manner. The answer contains evidence of application and interpretation. At the upper end there is evidence of thoughtful and measured critical evaluation.
70-79%	Demonstrates a clear, comprehensively researched understanding of relevant material with some element of critical evaluation. Shows initiative in approach and rigour in the handling of information. Demonstrates originality of thought together with interpretation and application to the relevant sector
80% or above	The answer is analytical and critical. The assignment demonstrates scholarship through a depth of insight and understanding of relevant material, which is logically structured, accurate and well referenced. Originality of thought and application is evident.

Case Study

LH Medical Company (LHM)

LHM is a London based privately owned hospital which provides health care to its patients. The hospital uses in-house software to manage and service its patients which they refer to as clients.  It is an expanding venture and needs to accommodate for processing its information globally. The practice management system is web-enabled and multi-platform for connectivity via web services, in addition, it has connectivity to existing legacy systems. An enterprise document management system ensures patient documents are replicated globally and available per demand.

In addition to medical treatments, medicine, and drugs, consultation and vaccinations are offered to its patients (with a variable additional fee) the company offers medical instruments to other companies either to purchase or to lease.

LHM records the details of its clients with possibly their full medical history in their computer system.  When a new patient requests an appointment (walk-in or online) a treatment course begins and a practitioner is allocated to the patient. A full history and previous medical records are printed showing different categories of Treatments during different time intervals. Analyses are drawn in terms of any possible allergies and previous histories. Treatments may involve many surgeons and consultants depending on its complexity.

The contact practitioner is responsible for estimating the costs of treatments that is agreed by the client at the start of the treatment. The duration of the treatment may be set at any time duration and may also be changed during the treatment depending on the complexity of possible operations.  The final cost and completion date are recorded at the end of the treatment.

During a treatment process, notifications may be sent to patients and other practitioners.

Repeat prescriptions may automatically be produced by the system if appropriate and are available for collection at any surgery by the patient. At any time a practitioner may suspend or cancel the prescriptions.

The cost for a treatment is paid for by the client or an insurance policy provided by a number of insurers. Insurance policies may have additional surcharges and cost depending on treatment types and medicines. Long-term treatment courses may be edited or canceled by practitioners or clients. To re-start an existing treatment an additional fee is applied.

LHM may receive requests for specialise treatments from other hospitals or they may refer clients to other medical centres.

Each treatment course or service may include one or more of the following items:

• Operations and vaccinations
• Consultations and check-up
• Medicine and different types of tablets
• Clinical reports and attached documents and history
• Prescriptions and repeat Prescriptions

Payments by clients may be in full or part payments to cover a range of medical and non-medical services offered by the company. Payments may include possible applied surcharges for late payments and or special discounts for long-term treatments.  Tax allocations may also vary from one treatment item to another.  Payments have to accommodate for price changes for medicines and medical services and track price changes for drugs purchased from pharmaceutical companies.

A treatment course comprising services from other hospitals carry additional changes set by the medical service providers. A full list of Treatment courses with corresponding payments may be requested by the site manager at any time. Clients' outstanding balances may be retrieved at any time for current treatment and services indicating the payments for the treatment course.
